Abstract

Perception of maxillary midline diastema as an esthetic trait varies in relation to culture, age group, and racial background. Although midline diastema is accepted in Africa, there are few reports on interethnic perception of midline diastema among Nigerians. Participants aged 19 to 45 years were selected from six geographical zones of Nigeria; one state was randomly selected from each zone, and a local government area (LGA) selected from each state. A structured questionnaire including a set of color smile photographs with varying sizes of maxillary midline diastema (narrowest=2 mm; widest=6 mm) was administered. Information sought was age, gender, socioeconomic group, tribe, presence of a midline diastema, and grading of attractiveness of smile. This information was evaluated using a Likert scale. A total of 402 subjects aged 19 to 45 years and a mean age of 36.3 years (±0.714) took part in this study. The highest proportion of subjects with midline diastema was aged 21 to 30 years (33.9%), females (29.8%), from the Hausa ethnic group (35%), and from the class II socioeconomic group (31.9%). Among the ethnic groups, Hausa had the highest (65%) preference for midline diastema. Females (58.8%) and those in the class II socioec...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
